How does SLR capture the details on the moon?

There are two essential elements in shooting the moon: the pixel is as high as possible and the focal length of the lens is as long as possible. Generally, if you want to shoot a crater, you must have a camera with more than100000 pixels and a focal length of more than 600 mm. Of course, a 600 mm fixed-focus lens will be more expensive. Another method is to add a 300mm lens and a 2x rangefinder. So the cost will not be too high. For example, Nikon's 300mm/4 with 2 times mirror, using D300 fuselage, the focal length can reach 900mm, enough to shoot a clear moon.

But if you want to shoot a clear and beautiful lunar crater, sharp and delicate, and look at the touching lunar quality, a 20-megapixel camera with a focal length of more than 800mm will be more comfortable.

Second, shooting skills

Location and time of shooting

To shoot the moon, you should first choose an open field, and it is best to choose a suburb with relatively transparent air to avoid the lighting pollution and air pollution in the city.

Pick a good day to shoot the moon.

Choose to shoot the full moon or string moon. Due to the influence of the sun on the angle of the moon, it is difficult to show the three-dimensional sense of the moon during the full moon. Generally, the crater at the junction of light and dark on the moon is the most obvious. If there is no dark side, it is difficult to photograph the crater. The stereoscopic impression of the moon is not obvious. Therefore, the moon is relatively round, and places with dark parts around the 13th and 17th lunar calendar are most suitable for shooting, which can not only clearly show the craters of the moon, but also make the moon three-dimensional.

Aperture and shutter

In order to make the photos clearer, it is best to choose an aperture of f/7. 1 or above, which can not only give full play to the quality of the lens, but also ensure the shutter speed. Different lenses have different apertures, and the imaging quality is the highest. You can try to find the most suitable aperture yourself.

In order to ensure the image quality, it is best to adopt a low ISO of 100 or 200.

concentrate

Nowadays, digital SLR cameras basically have the function of real-time viewing through LCD screen. This function is very useful in precise focus photography. You can use the autofocus function to focus roughly first. Enlarge and display the part you want to focus on through the LCD screen, and then focus accurately through manual focusing. Maybe zoom in ten times and you can see the satellite flying around the moon!

shoot

After the above preparations are completed, you should start the shutter. At this time, we must pay attention to whether there are cars or pedestrians passing by, which will also cause jitter, and then start the shutter when it is far away.
